Abstract

A push-to-talk communication device including an operating answer mode indicates that operating answer mode to a Session Initiation Protocol/Internet Protocol based push-to-talk network server. The method includes employing as the operating answer mode of the push-to-talk communication device one of an automatic-answer mode, an always-automatic-answer mode and a manual-answer mode.
